Going to a very basic question about a Storage Environment, What percent of your storage is allocated and what percent of it is actually being used?

The more utilization you gain, the further you can push your new storage acquisition timeframes increasing your ROI and reducing your CapEx. The better efficiency and optimization you gain in your storage environments, the further you can push to reduce your OpEx.

So based on some latest data we have gathered from various different customer environments, believe it or not, on an average, this is what we saw…..

 

Allocated Storage

Average Customer Production data: Between 20 to 24%

Average Copy / Replication data: 20% more than Production data: Between 24 to 28%

Raid Overhead associated with production data: Between 15 to 19%

Storage Allocated but no owners: Between 18 to 22%

 

Unallocated Storage

Storage unallocated meant for future use: 13 to 17%

 

To shed some light on production and copy / replication data, there are a lot of data inconsistencies being reported in terms of broken links, replication failures, source and bcv lun size mismatches, etc.

 


 

The above scenarios with allocated / unallocated storage will reduce your ROI (Return on Investment) and ROA (Return on Asset), further causing budgeting issues in an organization.  

As you go to various different teams and ask them about the allocated / unallocated storage, you will hear different answers throughout the entire organization. From everyone’s view these numbers are debatable.  

 

Experience:

This time around, a personal experience.

In addition to my Technology Solutions responsibilities for our customers, I also have responsibilities around managing internal IT infrastructure that includes the apps, databases , storage and other IT assets. We have a lot of new projects happening every month, quarter, etc and have to allocate storage for those needs.

Projects that are hot today, might not be hot in the next 3 months, or may be in next 6 months. Projects get scrapped, host systems get scrapped, but storage still sits there, churning and spinning. Believe it or not, as the economic times change, lots of things are enforced and as the IT managers internally started looking at all the storage, we were able to reclaim quite a bit that was in real terms stranded storage, which is now all allocated to new ongoing projects or ready to be allocated at a short notice.

Do you know how much of your storage today is allocated, unallocated, stranded and importantly how much of it is Production data in your environment?

We will continue our quest into Storage Economics with a few questions about our environments. If you are a storage administrator, storage architect, storage capacity planner, host administrator, member of CIO’s office, CIO, Strategic Planning and Buying teams, this post is for you. Based on your environments, organizations and business units, I would suggest you send these questions to at least 3 different teams that are related to storage and have them answer these questions. To your surprise, you will see the disconnect people within various different teams have based on the roles they play.  

So what are these fundamental questions? They revolve around your entire storage environment from your Storage Assets to your Storage processes like Tiering, Chargeback’s, Capacity Planning, Trends, Forecasting, Change Control, Provisioning, Service, purchasing, etc.


To discuss a few of them,

o   How much Storage do we have in our environment?

o   How much Storage do we have at various data centers we own?

o   How many Storage assets do we own? And what type of assets?

o   How much data (primary, replication) do we have at each data center?

o   How much storage growth did we forecast for 2008?

o   How much storage did the CIO’s office purchase in 2008? Are the numbers in line?

o   How much forecast do we have for this current year 2009?

o   When was the last time we purchased something because it’s a great toy to work and play with?

o   What is the % of our Storage Allocated?

o   What is the % of our Storage Utilization?

o   What % of our Storage is virtualized?

o   How do we measure our Storage efficiency?

o   How often do we run Storage optimization exercises?

o   How many hosts are connected to our Storage Environment?

o   Do we have a long term Storage Strategy in terms of growth, technology, direction, etc?

o   How many host systems do we migrate every week, month, quarter?

o   When was the last time after a host migration or host retirement, our storage was reclaimed?

o   Do we have a process around Storage Reclamation?

o   Is our Storage Strategy in line with our overall priorities?

o   Is our Storage being managed properly?

o   Is our Storage in line with what our Consultants have advised in the past?

o   When was the last time we had an Application Outage because of Storage?

o   What was the penalty our division paid for a human mistake?

o   What was the penalty our division paid for an application outage because of Storage mis-configurations?

o   Do we use Tiering in our Storage environment?

o   Do we enforce ILM in our Storage environment?

o   How much data based on Tiering do we have in our environment?

o   How many Luns are associated with a given host in our environment?

o   What host has the most amount of Storage allocated?

o   Do we replicate data for its criticalness?

o   Do we replicate data for Compliance?

o   When was the last time we verified our site to site replication is correctly working

o   Do we have islands of storage or centralized storage?

o   Are our BCV devices smaller than your source devices?

o   Are our BCV devices larger than your source devices?o   How do we do chargeback’s to the groups that use Storage?

o   Who paid for the last Storage hardware that was rolled into our datacenter? Who is actually using that Storage today?

o   Are we looking to purchase new Storage this month or quarter?

o   Do we need any independent help?

 

 

Experience

We manage some storage at a very large retail house. During a conference bridge meeting with the outsourcing partner of the customer who manages the entire Data center along with other storage islands, there was a basic question we asked the customer and the outsourcing partner, do you happen to know how many host systems are attached to this storage frame?

Answer comes back; it’s a development box, so we really don’t care. Upon further analyzing there storage environment over the next couple of days we found out that the customer had 82 host systems connected to this frame, primarily all classified as production data running on VMware and citrix infrastructure servers.


Would you like to know answers to all the questions above and develop an organization wide strategy about your Storage?

To list some very important items & agenda’s related to IT – Storage Budgets of 2009 are

 

  • Ø  Direct Impact Cost

o   Reducing Total Cost of Ownership

o   Reducing CapEx

o   Reducing OpEx

o   Storage Segment outsourcing

o   Reduce Cost of After Warranty Support

o   Reduction in Power Consumption

o   Reduction in Storage Management

o   Meeting SLA’s resulting in reduction in Penalties

  

 

  • Ø  Hidden Savings

o   Storage Virtualization

o   Increase Utilization & Efficiency

o   Storage Reclamation & Optimization

o   Redeploying unused storage

o   Trend Analysis and Forecasting

o   Unnecessary licensing cost for storage management software

o   Reduction in Floor Space

o   Centralized Storage

o   Storage Consolidation

o   Automation

o   Investment into long lasting technology

o   Planning resulting in future growth without heavy cost impact

o   Tiering using ILM approach

o   Green Data Center

 

Should I mention, “DO MORE WITH LESS”, the beaten up concept of 2009.

And the important aspect is how do you manage to achieve all of the above while your databases are growing, your file systems are growing and you do not have a luxury to spend any additional dollars this year?


Experience

Recently I had a chance to talk to a CIO from a Fortune 1000 customer, and during the conversation with him, we asked him about what the primary objectives he has for his organization related to Storage.

Some of the things he mentioned were increasing efficiency and utilization within his storage environments, reducing his OpEx with automation and consolidation, reducing his CapEx with leveraging his IT assets on the floor for 3 additional years after warranty and try to centralize the entire storage throughout all business groups for better management and OpEx/CapEx reduction.

 

Well, let’s move on to the next topic…….

What have you or the top management done in your organization to meet the IT – Storage budgets of 2009?

o   Business Process Data

 

While we talk about the IT – Storage Industry and its surrounding requirements and impact, we need to know the Storage Economics behind it.


While the File Systems are consistently growing, Databases are exponentially growing, Compliance is a must and business processes are becoming critical every day, how do we manage and leverage what we have plus help reduce CapEx / OpEx and still manage to keep uptime/ efficiency / utilization.


Example:

I recently had a chance to visit a MNC (Multi National Company) to talk about Storage. We had long 6 hour meetings with various Application Owners, Business Group Owners, Strategic Planning folks, member’s from the CIO’s office, Storage Administrator and Host Administrator. During these sessions, we asked them a few basic questions about their Storage environments related to usage, outages, charge backs, new acquisition, storage management, process management, etc.

It was very surprising to see disconnect of priorities that various different teams had based on the role they played in that organization. Certain folks were talking about budget reductions, while some had priorities to play around with the latest technologies, while some had priorities about the application uptime, while some were focused on growth and some thought about ease of use.

But during the entire time we did not hear any common messages from these various teams about efficiency and optimization of their Storage Environments …….


Well, let’s move on….

What do you do to keep up with the IT – Storage requirements?

Is someone helping you purchase new Storage?
